Back in 2016, we carried a feature looking at 5 music software that were highly promising. The five music programs are qomp, Lollypop, Yarock, Pragha, and Volumio. How did these 5 music players fare over the last 4 years? Did they see a stable release, were they able to capture any market share at all, or are they only remembered like fingerprints on an abandoned handrail?
